The cost of upgrading to the EPIC for me

[masetas]

Trying to decide if i upgrade to the Epic from the TP2. im still not fully decided because im waiting to see actual consumer comments on it. what will come out after it. I know HTC has to come out with a Full qwerty keyboard for Sprint atleast by the end of this year ready for the holidays.
But the real reason why im not decided yet is because TP2 works perfect it does everything i need when im out the office and for personal use Epic would just be more of a want than a need also because of the following

Sprint Tp2 on boost Sprint Epic 4g (contract )
$50 Mnth Unlimited $80 Mnth
x12 Mnths x12 Mnths
-------- -----------
$600 $960 = $360 more a year plus let say the phone cost $200 with a new contract
